Because to see the improvement in fuel economy you have to drive it harder...duh!
They were unable to even dyno a 5th gen 4Runner (attempt was made), but the data is ‘theoretical’ just like global warming

It's good to see that I am not the only one with this spread sheet
So far the data is consistent, and all of it is pointing towards the same conclusion. I can't thank you enough for spending your time gathering this data for the community.

Final results ecoblock
Here are the final results comparing the MPG with the Crawford Ecoblock and running the 4Runner Stock. Big thanks to [MENTION=152509]ayeyothisiskyle[/MENTION] for taking my data and putting it into a spreadsheet! Kyle - if you want to link the spreadsheet to this thread feel free to do so, I couldn't get it done and just made it into a pdf.

OK, the MPG results are in for your 6 tank informal test.
With EcoBlock overall total MPG Average = 17.07, without EcoBlock = 16.3. Difference = 0.77.
If you look at your City data you can see that with your driving habits and routes you get 15.9 MPG with and 15.4 MPG without. Difference =0.5.
If you do any Highway driving in the mix you get 18.2 MPG with and 17.24 without. Difference = 1.
Not very impressive, the results are actually in the noise.
However this does give you a rough idea of your particular truck, route, driving habits, fuel, etc.
16 MPG city, 18 MPG city/hwy combined. Too bad you did not have any pure highway tankfuls.
The Toyota MPG estimates (for ORP) city/hwy/combined are 17/20/18. So you’re just about in the average range. Be happy. ��
Conclusion: EcoBlock makes no big difference.

1MPG would be a huge deal. Toyota would spend tens of millions of dollars to get 1mpg improvement. And that's why it's easy to reach the obvious conclusion that this product doesn't work. Toyota has unlimited access to the ECU and can tune it any way it wants. If it were possible to increase MPG while not violating emissions rules or degrading engine life - Toyota would be doing it. Obviously such a small data set is problematic as far as reaching a conclusion - I'll do a regression analysis when I have a minute ( to see how much is predicted by driving time, I don't think subjective city/highway has any value) and calculate the minimum sample size to identify a 0.1mpg difference. I'm guessing it's in the hundreds of tanks if not thousands.
The tragedy is that someone will consider this a validation of the claims - and anyone with a shred of mathematical skills would know that this is not that. Nor would the reverse have shown that it doesn't work. It's simply not enough evidence to reach any conclusion.

Just saying. For this to be statistically significant, you need a lab or hundreds of thousands of miles of data. I appreciate his effort, but unfortunately it says nothing. For all we know, the change in MPG could be the air temperature that day, or maybe he just had too much coffee on the low-MPG days
This is exactly correct. If Toyota didn't settle on a tune that offers what this claims to offer, there's a reason for it. I'm looking forward to the first receipt for a cat replacement.

My personal take on it [MENTION=118321]Jetboy[/MENTION] is that driving time (to an extent) has everything to do with MPG and not the % city/highway. This was really just for me to see what the ecoblock would do for my particular situation.
I don't think that the MPG is a significant increase, but I will be putting it back on because for me it's about 1 gallon per tank better.
I agree that having a 5 hour trip on the interstate would be interesting to see, just wasn't in the cards for this short test.

Thank you for collecting the data! There's not a lot we can tell from it. It would take between 200 and 500 tanks to prove a difference in mpg if the samples are representative of typical variation depending on how confident we want to be. But it's better than nothing.
But just for fun:
The best fit linear formula for this data is 11.45 + (mph*.220925). The mph average is a significant predictor of mpg. As you would expect. The problem is that it's not a linear relationship between speed and mpg as we all know from experience. Wind resistance is exponential. And stop and go driving is also inefficient. So peak MPG is somewhere in the middle.
The only real anomaly is fillup 1 with ecoblock. It was the only tank out of all 12 that was nearly 1mpg better than expected based on the linear formula (that we know is wrong anyway, but still a fit - meaning we know our data isn't giving a full picture). If the computer learns around it - it does it in 1 or 2 tanks. Tanks 4,5, and 6 are nearly identical to expected along with all the tanks without the ecoblock. It's easy to speculate that the ECU corrected for it in 2-3 tanks, but that's purely speculation. We can't say with any confidence that any tank was any different from any other.

Thanks for your time checking the results of our Eco Block Fuel Saver on your truck. What we promote / see is a 7% average increase in fuel mileage and a 5% average increase in power and torque.
Your particular vehicle and driving style have shown closer to a 5% increase in fuel mileage which is still well worth the minimal cost of our Patented fuel saving device, and this is also a larger increase than any other fuel saving device you can purchase at any price!
Again, thanks!

No. This hasn't been shown. The data does not support a claim that there is any difference. Statistics 101.

Hey, that’s great!
We’ve all been struggling trying to prove to ourselves with our simple MPG tests that the EcoBlock really works.
I’m sure you’re manufacturer’s test suite is much more thorough than any user testimonials and will provide all the proof we need.
Please provide us with your test result documentation so we can be convinced. With those proven results I’m sure you’ll get lots of customers!
Right. I'm sure there's lab results that will not only convince us to buy it, but will come handy to make sure things run super smooth should EPA open an investigation (as they tend to do with devices that specifically alter regulated emissions controls).
